In an attempt to assess the value of preoperative tubal testing in the selection of cases most likely to respond favourably to surgery, 100 ears with a central perforation following chronic otitis media were investigated. Tubal function was tested manometrically with different known tests. Postoperatively the healing and hearing results were correlated with the preoperative test results. No positive correlation was found between healing or hearing and tubal function. Postoperatively 50 ears were re-tested in a pressure chamber with a flow volume technique. It was found that the tubal function improves postoperatively in spite of no visible pathological changes in the aural end of the tube. Possible explanations are offered.
为了评估术前输卵管检查在选择最有可能对手术产生良好反应的病例中的价值，对100例慢性中耳炎后中央穿孔的耳朵进行了研究。通过不同的已知测试以压力测量法测试输卵管功能。术后将愈合情况和听力结果与术前测试结果进行关联。未发现愈合或听力与输卵管功能之间存在正相关。术后，用流量容积技术在压力室对50只耳朵进行了重新测试。结果发现，尽管在咽鼓管的耳部末端没有明显的病理变化，但术后输卵管功能有所改善。文中给出了可能的解释。
